It's a joke about how a Russian, an American and a Japanese were given each 2 metal balls in order to test their abilites. They were locked in separate rooms without any windows, doors or even cracks. After 2 days they (who tested) came to see the results. The american is juggling with balls. Ok then. The Japanese is juggling, dancing and singing at the same time. Excellent. Then they came to test the Russian. 1 hour passes... the 2nd our passes... They go out and say:"The Russian has won!" "Why so?" "Because he BROKE the first ball and LOST the secind one."
